How to run php cli script from browser if exec fails?

Question

PHP

There is an online store import script written in php cli.
It is necessary that a person could run it not from the command line, but simply by clicking on the link.
exec is enabled, but exec('/usr/bin/php %reference to full path to script% < /dev/null > import.log &', $output); gives no effect.
What could be the problem? The file permissions are correct.

Answer 1

What effect do you expect? You have all the output redirected to a file, plus the ampersand at the end takes the script into the background. Accordingly, there will be nothing in the $output variable.
